Being qualified MCA through distance mode from IGNOU, can I study MS in US?
Would there be any problems as MCA was done through distance mode?
Also tell me the expected cost to arrange for the requirements before applying for us colleges.
Any financial support mandatory for visa?
Well, it depends on if your degree is recognized well by the foreign university. Typically US schools look for degree equivalence with their bachelors degree. There is no generic answer, you need to check with the schools you plan to apply to get a concrete answer.
Again, not sure, you need to check with the schools you intend to apply

The schools will ask for financial support before they issue admission I20.
